What We Do
Sauna builder services for home installation across Orange County
Newport Beach Sauna is a licensed builder that carries the whole job: design, permits, framing, insulation, vapor barrier, ventilation, heater installation, finish carpentry and the first heat cycle. We build traditional Finnish rooms with real löyly, infrared and hybrid cabins, steam saunas and steam showers, barrel saunas, indoor conversions and outdoor cabins, and we install cedar tubs and cold plunges alongside them. Building within a mile of the water changes the specification more than most people expect, and we spec for it: marine-grade fasteners, stainless bands, corrosion-rated heater housings and a vapor barrier detail that assumes the marine layer is going to test it every single night. When something stops working, in a room we built or one we did not, we repair it. A single project manager, a single fixed price and a single crew, from the first tape measure to the day you sit in it.

Corona del Mar, CA
Corona del Mar Cedar Room
Master-bath conversion in clear western red cedar with a 9kW electric heater and a full-glass cedar-frame door. Reaches 195°F in half an hour on a panel that needed a subpanel first.

Why Choose Newport Beach Sauna
We are a professional sauna builder, not a general contractor who takes the occasional sauna job. The difference lives in the parts of the build you never see again once the paneling goes up: a continuous foil vapor barrier lapped and taped at every seam, intake and exhaust placed where they will actually move air, heaters sized against the real cubic volume and glass area of your room, and benches set to your ceiling height so the top bench sits in the hot layer instead of below it.
- Licensed, insured and permitted. California Class B general building license, insured and bonded, with every electrical and building permit pulled and inspected rather than quietly skipped.
- Built for the coast. Salt air eats hardware. We specify stainless and marine-grade fasteners, corrosion-rated heater housings and sealed exterior penetrations as standard, not as an upgrade line item.
- One crew, one number. Drawing, approvals, framing, wiring, carpentry and commissioning all sit with us. Nothing gets handed between trades and nothing falls through the gap.
- Flat-rate quotes. The number you sign after the design phase covers the heater, the wood, the wiring, the venting and the permits. Nothing new appears on the final invoice.
- Every heat type. Electric and wood-fired traditional rooms, infrared, hybrid and steam. We are not tied to one manufacturer, so the recommendation follows your room rather than our inventory.
- Materials that belong in a hot room. Clear western red cedar, hemlock, Nordic spruce, thermo-aspen and abachi. No chemically treated framing lumber anywhere the heat can reach it.
- We come back. The same crew services what it builds, and we repair other builders’ rooms too, which is the best education available in what fails and why.

Our Mission
Build the best saunas in Orange County, and build them so a room installed today is still worth using in twenty years. Newport Beach took to the wellness side of sauna early and there are a lot of expensive rooms along this coast that never quite reach temperature, benches set at the wrong height, and cedar going black behind a vapor barrier that stopped six inches short of the ceiling. We would rather talk a client down to a smaller heater than sell a bigger one, and we would rather push a start date than close a wall we are not happy with. Every homeowner who calls gets a straight answer about what their space can and cannot support, whether or not that answer ends in a sale.
Why Choosing the Right Sauna Builder Matters
Nearly everything that determines whether a sauna is any good is covered up before you ever see the finished room. That is what makes this a hard thing to buy well, and it is why the cheapest quote on the table is so often the most expensive one in the end.
- Unpermitted electrical. A 60-amp heater circuit run without a permit is a fire risk, an insurance problem and a disclosure item at resale, and it is the first corner cut on a low bid.
- A vapor barrier that stops short. Skip it, puncture it, or run it to within a foot of the ceiling and moisture moves straight into your framing. In this climate you find out in two or three winters, and by then the repair is a rebuild.
- Ventilation treated as optional. With no intake below the heater and no exhaust on the far wall the air goes flat, the room smells inside a year, and the floor stays cold while the top bench cooks.
- Hardware that was never rated for salt air. Zinc screws, mild-steel bands and an unsealed flue penetration will look fine on handover day and be weeping rust by the second summer on any lot within a mile of the sand.
- A heater sized off a chart. A glass door, an uninsulated outside wall and a tall ceiling each add to what the heater has to overcome. Pick the heater on square footage alone and you get a room that never quite arrives.
- Bench height guessed at. Heat stratifies hard. A bench set without reference to the ceiling puts your head in the cool layer, and no heater on the market fixes that afterwards.
- Treated lumber and sealed finishes. Pressure-treated framing and varnished linings both give off fumes once the room is at temperature. Neither belongs near a hot room, and both turn up in DIY builds constantly.

What Affects the Cost of Sauna Installation
Installation pricing moves with the size of the room, the heater and how much of the existing space has to be rebuilt. The main drivers:
- Room size. Four feet by five, seating two, is where this starts. A 6×7 four-person room is our most common build. Family-size and outdoor rooms scale up from there.
- Heater type and output. A 6kW electric sauna heater is the value option. A wood stove brings a flue and a combustion approval with it. Heaters with air circulation and humidity control occupy the upper end.
- Electrical distance and panel condition. A short run to a nearby subpanel is a modest line item. A long run through finished walls, or a service upgrade on a 100-amp panel, is not.
- Wood species. Western red cedar is the benchmark. A hemlock sauna comes in slightly under it. Thermo-aspen and abachi are the premium tier for benches that stay cool to the touch.
- How much rebuilding is needed. A framed, insulated space ready to receive paneling goes fast. A garage bay with bare studs, no insulation and no vapor barrier does not.
- Permits and coastal review. Electrical permits apply to every install. Framing changes and outdoor structures add a building permit, and coastal-zone lots may add a CDP. All quoted up front, never added later.

Installation is quoted flat-rate after the site visit. Heater, wiring, venting, permits and the first heat-up are inside that number, and the same basis applies to Commercial Saunas once the drawings are settled.

Frequently Asked Questions
How much does a home sauna installation cost?
In Orange County most home sauna installations land in a wide band depending on room size, heater choice and how much of the space has to be rebuilt first. A small two-person conversion inside an already framed closet is the low end. A six-person cedar room with a premium heater, a new circuit and a full glass door is mid-range. Outdoor cabins with footings, a roof and a trenched electrical run sit at the top. We quote flat-rate after a site visit, with the heater, wiring, venting and permits all included, so the number you approve is the number you pay.
What are the electrical requirements for a sauna heater?
Almost every electric sauna heater needs a dedicated 240V circuit with nothing else on it. A 4.5kW heater typically wants 30 amps, a 6kW heater 30 to 40, an 8 to 9kW heater 40 to 50, and a 10.5 to 12kW heater 60. Wire gauge is sized for the run length, and the heater is hard-wired rather than plugged in. We check panel capacity before anything else, because a lot of the older housing stock on the peninsula and in Corona del Mar is still on 100-amp service and needs a subpanel or a service upgrade before a large heater is realistic.
Can I install a sauna without a permit?
Not legally, and not safely. The dedicated 240V circuit needs an electrical permit in every Orange County jurisdiction we work in. Framing a new room or putting up an outdoor structure adds a building permit, a wood-fired heater adds combustion and venting review, and a lot inside the coastal zone can require a Coastal Development Permit on top. Unpermitted work becomes a problem at resale, during an insurance claim, or on the day something fails. We pull every permit as part of the install and run the inspections.
How long does a sauna installation take?
An indoor conversion in a space that is already framed usually runs one to two weeks on site once materials land, plus permit lead time. Converting a whole closet or a garage bay takes two to three weeks. Outdoor builds with footings take four to six. The heater and wood order is normally the longest lead item, so we place it the day the spec is signed rather than waiting for the permit to clear.
Which brands provide eco-friendly sauna heaters and steam generators?
We install across all the major brands and can spec an efficient unit within any of them. On the electric side, look for a well-insulated cabinet, high stone mass and a modern digital control with a scheduling timer, because holding heat efficiently matters far more than the nameplate rating. On the steam side, look for auto-drain and auto-flush generators, which use less water and last considerably longer given how hard the water is here. We are not tied to a manufacturer, so the recommendation follows your room and your budget rather than our stock.
